Wow, look at that picture! An orca drives a dolphin out of the water during a chase. Reporters suggest this is the first time people have ever observed orcas hunting their cousin, the dolphin.
Off South Africa, 6 people watched a group of 5 orcas cooperate in hunting and killing a dolphin. Then they got in the water with the orcas, who wouldn't?
The dolphin in the picture was a lucky one that got away, but another dolphin from the same group was later killed.
